Desempenho produtivo da serigueleira no quarto ano de cultivo.

Abstract

The serigueleira, scientifically called Spondias purpurea, is a fruit tree, originally from Central America, but can be found in South America. In Brazil, it has an incidence in the North, Northeast and Southeast, specifically in the Northeast as it has a good acceptability in consumption and marketing. The objective of this research was to evaluate the productivity of the seriguela crop with different lengths of cuttings, in addition to analyzing the growth of the stem rings of two variables through the calculation of growth increment; verifying the correlation between stem diameter, production and productivity; record the occurrence of insects, pests and diseases in the crop. The experiment was carried out in the municipality of Jaçanã-RN on the Chã da Bulandeira property. The experimental area was divided into four randomized blocks with five treatments, being T1: 0.8 m, T2: 1.0 m, T3: 1.2 m, T4: 1.4 m, T5: 1.6 m. The variables studied were fruit productivity, growth increment, stem diameter, production, and the occurrence of insects, pests and diseases. The data were subjected to analysis of variance and the means compared by the test Tukey's, through the SISVAR computer application version 5.6. In the analysis of the collected data, it shows that in the fourth year of cultivation it presented efficient performance, as the productivity of the Spondias purpurea crop remains, considering the T4 and T5 that stood out with greater production, regarding the increase in growth, it was possible to calculate the growth of the stem diameter from two variables, the correlation between the stem diameter, production and productivity is perfect and positive, but relatively weak. However, shows a significant association between two variables, thus production and productivity depend on the stem diameter and the occurrence of insect pests and diseases was observed in the experiment, such as termites that attack the plant in a damaging way, compromising the parts woody; arapuá bees that attack the fruits and powdery mildew spots that negatively interfere with the development and commercialization of the fruit.
